Page 26: Testing Of 110V Appliances
3.7 Testing of 110V Appliances A TL157 PAT 110V Adaptor (available separately) is required for testing 110V appliances (yellow BS 4343 16A 110V plug). Refer to the connection diagram below. TL157 110V adaptor Ensure that the appliance is switched ON. Undertake a test sequence as appropriate for the appliance (See 3.1 to 3.4). - Page 27 For this reason, the test of a 110V appliance using the TL157 will always result in a FAIL at the Load check. Check that the appliance is switched ON. Begin the test again if necessary. The user should also have checked the fuse (if fitted). Assuming such checks above have been made, the Class I or Class II appliance test sequence can be continued beyond the simulated load check result by selecting Continue.
